Description

Technical Field

On the one hand, users care about the pure electric driving range of extended-range vehicles and expect the vehicles to have stronger electrification properties. Maintaining the battery power in a high range can provide more functions and better performance. Therefore, the method of starting the range extender to remotely recharge the battery can conveniently increase the battery power, which can not only solve the problem of scarce charging pile resources, but also charge the battery quickly and efficiently, improving the user's driving experience. On the other hand, users care about the intelligence of the vehicle. By providing a remote battery recharging operation interface, such as a mobile device APP, the user's operation interaction experience can be improved, and the intelligent performance of the vehicle can be improved.

[0003] For extended-range electric vehicles, the power battery is generally charged by connecting to a charging pile or starting the range extender. Charging with a charging pile is a more common way to charge, but it cannot meet the user's charging needs when there is a lack of charging pile resources or a partial failure of the charging system. At this time, using the range extender to actively generate electricity to charge the battery becomes a good emergency charging method.

[0004] In the prior art, the range extender can only recharge the battery when the vehicle is powered on. When the battery has a large recharge demand, the vehicle needs to remain powered on for a long time, which indirectly requires the user to stay in the vehicle for a long time, causing great inconvenience to the user.

[0043] In order to facilitate understanding of the present invention, several embodiments of the present invention are provided below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0044] Embodiment 1

[0045] The first embodiment of the present invention provides a method for controlling the remote charging of a power battery of an extended-range electric vehicle, the method comprising steps S101 to S106:

[0046] S101, obtaining vehicle surrounding environment information.

[0047] S102: Determine whether the surrounding environment information satisfies a condition for enabling a remote power replenishment function.

[0048] Specifically, the remote terminal APP sends the vehicle surrounding environment monitoring instructions to the vehicle remote communication module; the vehicle power replenishment control module receives the vehicle surrounding environment monitoring instructions forwarded by the vehicle remote communication module, calls the vehicle panoramic imaging module, and sends the vehicle surrounding environment image information to the vehicle remote communication module, and the vehicle remote communication module then uploads it to the remote terminal APP to view the vehicle surrounding environment image information.

[0049] During the specific operation process, the user can also zoom in and out the image of the vehicle's surrounding environment for clear and accurate viewing. Based on the viewed image information and the reminder text on the remote terminal APP, such as "Please ensure that the vehicle is not in a sealed space and there are no flammable and explosive items around the vehicle", the user determines whether the vehicle's surrounding environment is suitable and decides whether to turn on the remote charging function. If the user turns on the remote charging function, the charging mode is selected, otherwise the remote charging function is not turned on. Optionally, regardless of whether the charging function is turned on or at any time during the charging process, the user can view the image information of the vehicle's surrounding environment at any time.

[0050] If the remote power replenishment function activation condition is not met, step S103 is executed;

[0051] If the remote power replenishment function activation condition is met, step S104 is executed;

[0052] S103: The remote charging function is not enabled, and the reason for not allowing the vehicle to enable the remote charging function is processed into function reminder information, so as to feed back the function reminder information to the remote terminal APP through the vehicle remote communication module; wherein the function reminder information includes that the current fuel level is low and the remote charging of the power battery cannot be enabled.

[0053] S104: Turn on the remote power replenishment function and select a power replenishment mode to output a remote power replenishment instruction.

[0054] S105. Determine whether the vehicle meets all charging conditions according to the remote charging instruction.

[0055] The conditions for power replenishment include:

[0056] 1) The power replenishment function is turned on;

[0057] 2) The vehicle is stationary and the speed is ≤ the speed threshold;

[0058] 3) The vehicle gear is in N / P gear;

[0059] 4) Vehicle power OFF position sent by the body control module;

[0060] 5) The vehicle sent by the body control module is in the armed and locked state;

[0061] 6) The battery power sent by the power battery module is ≤ the first power threshold;

[0062] 7) The battery rechargeable power sent by the power battery module is ≥ the rechargeable power threshold;

[0063] 8) The remaining fuel volume sent by the range extender module is ≥ the first fuel volume threshold;

[0064] 9) Failure of the unlimited range extender sent by the range extender module to work properly.

[0065] If satisfied, execute step S106;

[0066] S106, starting the vehicle range extender module to supplement the power of the vehicle, and monitoring the real-time status of the vehicle until the vehicle fails to meet the supplementary power conditions, the vehicle range extender module stops generating power, the vehicle exits the supplementary power function, and does not continue to supplement power.

[0067] The charging control module sends a command to allow the vehicle to start remote charging and a charging mode command to the range extender module. The range extender module generates electricity according to the charging mode, and the power output is transmitted to the power battery module through the high-voltage circuit. As a specific example, the remote terminal APP has a switch to turn on the remote charging function, and the charging mode can be further set. Specifically, the remote terminal APP provides two charging modes, standard and fast. The charging powers of the two modes are different, and they are applied to two scenarios: conventional charging and fast charging. The two charging modes here correspond to the two range extender power generation working points preset in the range extender module. The power battery module feeds back the battery power and battery rechargeable power to the charging control module in real time.

[0068] The standard charging mode corresponds to the working point of the range extender with low power, low noise and moderate fuel consumption, and is used in conventional charging scenarios. The fast charging mode corresponds to the working point of the range extender with high power, medium noise and low fuel consumption, and is used in scenarios where users need to charge quickly. Through differentiated charging mode settings, different charging needs of users can be met.

[0069] Specifically, monitoring the real-time status of the vehicle includes: feeding back the charging function execution status information to the remote terminal APP in real time through the vehicle remote communication module, and the status information includes: charging in progress, charging failure and charging completion.

[0070] Furthermore, after the step of stopping power generation of the vehicle range extender module, the step further includes: feeding back the conditions for terminating the remote power replenishment of the vehicle to the remote terminal APP through the vehicle remote communication module, and the conditions for terminating the remote power replenishment of the vehicle include that the battery power has been charged to a preset value and the power battery power replenishment is completed. For example, when the preset value is 90% of the full power, the vehicle range extender module stops generating power when the battery power is charged to 90%.

[0071] When the vehicle does not meet the charging conditions, it can be understood that when any of the following conditions are met, the vehicle charging control module prohibits the vehicle from starting remote charging, specifically:

[0072] 1) The remote power replenishment function switch sent by the remote terminal APP is turned off;

[0073] 2) The vehicle is not stationary and the speed is greater than the speed threshold;

[0074] 3) The vehicle gear is not in N / P gear;

[0075] 4) The vehicle power sent by the body control module is not in OFF position;

[0076] 5) The vehicle sent by the body control module is in a non-defended locked state;

[0077] 6) The battery power sent by the power battery module is ≥ the second power threshold;

[0078] 7) The battery rechargeable power sent by the power battery module is less than the rechargeable power threshold;

[0079] 8) The remaining fuel volume sent by the range extender module is ≤ the second fuel volume threshold;

[0080] 9) The range extender module sends a fault that limits the normal operation of the range extender.

[0081] Among them, the first power threshold, the second power threshold, the first oil level threshold, and the second oil level threshold can all be preset in the control module, and can also be set on the remote terminal APP.

[0082] In summary, the remote charging control method for the power battery of an extended-range electric vehicle in the above-mentioned embodiment of the present invention obtains a remote charging instruction; determines whether the vehicle meets all the charging conditions according to the remote charging instruction; if satisfied, starts the vehicle range extender module to charge the vehicle, and monitors the real-time status of the vehicle until the charging conditions of the vehicle are not met, the vehicle range extender module stops generating electricity, the vehicle exits the charging function, and does not continue to charge; on the one hand, the present application can set different charging modes through the remote terminal APP to deal with conventional charging and fast charging scenarios respectively; on the other hand, by calling the vehicle panoramic imaging module, the user can check the vehicle environmental conditions at any time when needed, realize vehicle environmental monitoring, and improve the safety of long-term startup of the range extender in an unattended state.

[0083] Embodiment 2

[0084] See also Figure 1 , shown is a remote charging control system for a power battery of an extended-range electric vehicle in a second embodiment of the present invention, comprising a remote communication module, a panoramic imaging module, a body control module, a charging control module, a thermal management module, an air conditioning module, a power battery module and a range extender module connected via a CAN bus, the system further comprising a remote terminal APP, the remote terminal APP being wirelessly connected to the remote communication module;

[0085] Among them: the remote communication module is used to forward the interactive information between the remote terminal APP and the charging control module, and is responsible for controlling the vehicle wake-up; the panoramic imaging module is used to obtain the vehicle's surrounding environment information for the user to determine whether to turn on the battery remote charging function; the body control module is used to monitor the vehicle power status and door lock arming status, and is used to determine whether the battery remote charging function is turned on or off; the charging control module is used to monitor the vehicle status information, judge the battery remote charging, air conditioning heating, and battery heating conditions, and feedback the function execution status and function reminder information; the thermal management module is used to respond to the thermal management requirements of the air conditioning module and the power battery module, control the thermal management loop, and realize the waste heat utilization of the range extender module; the air conditioning module is responsible for the air conditioning heating process control, and cooperates with the thermal management module to heat the passenger compartment; the power battery module is responsible for the battery heating process control, and cooperates with the thermal management module to heat the battery; the range extender module is responsible for feedback of the oil volume, system fault information and power generation process control, and outputs high voltage electricity to the power battery; the remote terminal APP provides a power battery remote charging setting interface, and feedbacks the setting status, function execution status and function reminder information to the user.

[0086] In some optional embodiments, when the user turns on the remote charging function on the remote terminal APP, he or she can further choose whether to turn on air conditioning heating and battery heating. Air conditioning heating and battery heating are independent of each other, and can be set separately on the remote terminal APP to turn on or off. The remote terminal APP sends air conditioning heating and battery heating switch status instructions to the vehicle charging control module. The vehicle charging control module receives the air conditioning heating and battery heating switch status instructions forwarded by the vehicle remote communication module, and controls air conditioning heating and battery heating in combination with whether the vehicle charging control module allows the vehicle to turn on remote charging. If the vehicle charging control module allows the vehicle to turn on remote charging, it sends instructions to the air conditioning module and power battery module to allow the vehicle to turn on air conditioning heating and battery heating. Otherwise, the vehicle does not perform air conditioning heating and battery heating.

[0087] The air-conditioning module is responsible for judging the conditions for starting the vehicle's air-conditioning and heating. When the conditions are met, the thermal management module activates the air-conditioning and heating control and uses the heat generated by the range extender module to heat the passenger compartment.

[0088] The power battery module is responsible for determining the conditions for starting battery heating in the vehicle. When the conditions are met, the thermal management module activates the battery heating control and uses the heat generated by the range extender module to heat the battery.

[0089] During the air conditioning and heating process, the air conditioning module determines the conditions for turning off the air conditioning and heating of the vehicle in real time. When the conditions are met, the thermal management module terminates the air conditioning and heating control.

[0090] During the battery heating process, the power battery module determines in real time the vehicle's battery heating shutdown conditions. When the conditions are met, the thermal management module terminates battery heating control.

[0091] The vehicle charging control module receives the heating status information sent by the air-conditioning module and the power battery module, and feeds back the heating function execution status information to the remote terminal APP in real time through the vehicle remote communication module, such as the power battery is heating, heating fails, heating ends, etc.

[0092] In this application, when the user turns on the charging function in the remote terminal APP client, he can also set the air conditioning heating and battery heating to start simultaneously. The range extender generates heat during the charging process. When the air conditioning heating and battery heating are turned on, the heat generated by the range extender module can be effectively used to heat the passenger compartment and battery. While realizing the utilization of waste heat, the user experience is improved.

[0093] In summary, the remote charging control system for the extended-range electric vehicle power battery in the above-mentioned embodiments of the present invention obtains a remote charging instruction; determines whether the vehicle meets all the charging conditions according to the remote charging instruction; if satisfied, starts the vehicle range extender module to charge the vehicle, and monitors the real-time status of the vehicle until the charging conditions of the vehicle are not met, the vehicle range extender module stops generating electricity, the vehicle exits the charging function, and does not continue to charge; on the one hand, the present application can set different charging modes through the remote terminal APP to deal with conventional charging and fast charging scenarios respectively; on the other hand, by calling the vehicle panoramic imaging module, the user can check the vehicle environmental conditions at any time when needed, realize vehicle environmental monitoring, and improve the safety of long-term startup of the range extender in an unattended state.
